` e Claims. '(ol. 15-20) This inventionl relates 4to yirriprovement's in Ament 8 together with an extension 'rod 9 having method of'and: apparatus for removing oily cara crank or hand--wheel 10 situated outside of bon and soot deposits from the interior of smoke the stack is provided for rotating the perforated stacks and the like, and relates more particupipe when desirable. A nozzle 11 for directing i 5 larly to a method of delivering and distributing a plurality of streams of steam to the walls of 60 a plurality of streams of air or steam to an the breeching is secured to the lower end of the area to be cleaned and to apparatus for accompipe 1. rplishing the same. Referring now to Figs. 2 and 3 as well as to n When closing off the fires in the boiler fur- Fig. l, a swivel T arrangement is provided which T naces of a Steamship oily carbon and soot will rigidly attached to the inner termination of 65 be deposited or lodged on the inner wall of the the steam supply pipe 6, through which the stack and on adjoining portions of the breechperforated pipe 1 is rotatably passed. The roing and frequently some of the deposits grow to tatable pipe 1 preferably is provided with collarconsiderable size. When the fires are later startlike members which are rigidly attached y 1'5` ed up bits of the material, most of which is thereto and which support the T arrangement 70 burnable, will ignite and sparks are thrown out and projection of the pipe 6 so as to maintain of the stack and occasionally burning masses the T in proper vertical alignment Ywith the pipe 0f the SOUJGY SUbSaHC@ WhiCh have Dl'eVGuSly l. llhat portion of the pipe 1 which is encased escaped burning may be blown out of the stack by the T has several slots or openings 6a so that 120 and about the deck of the vessel. steam supplied from the supply pipe 6 may flow 75 The chief objects of this invention are to effecfrom the chamber of the T into the perforated tively remove vall of the carbon or soot which pipe. The swivel T is provided with suitable collects in a stack prior to the firing up of the packing glands at its upper and lower extremifurnaces and to provide adequate apparatus ties, that is its running ends, so that substancapable of being operated upon proper occasion tially no steam will be lost or wasted between 80 for that purpose. rl'hese and othel` objects and the peripheral wall of the pipe 1 and the encasuses of my invention will become apparent from ing walls of the T.

To aid the upward while a suitable bevel gear and bracket arrange-` movement in the stack of the material being blown out it may be desirable in some cases to drill the perforations slantingly as shown in Figure 4 so that the streams of steam may be directed slightly upward as well as outwardly against the wall of the stack.

While the steam inlet and the gear arrangement is shown near the base of the stack it may be preferable in some cases to situate these parts near the top, that is, above the indicated poop deck level where the temperature Within the stack may be somewhat lower and the deteriorating effect of the flue gases upon these members be less severe.

It is obvious that many minor changes may be made in the form and construction of the apparatus without departing from the material principles thereof. It is not therefore desired to confine the invention to the exact form herein shown and described, but it is wished to include all such forms as come Within the scope of the claims.

What I claim is:

1. In combination with a smoke stack, a centrally disposed rotatable pipe mounted within the stack and extending substantially the length thereof, said pipe being provided with upwardly slanting perforations throughout its length, a uid supply pipe extending through the wall of the stack, a fluid-tight connection between the supply pipe and the perforated pipe, and means for rotating the perforated pipe.

2. In combination with a smoke stack, a. centrally disposed rotatable pipe mounted within the stack and extending substantially the length thereof, said pipe being provided with upwardly slanting perforations throughout its length, a fluid supply pipe extending through the wall of the stack, a fluid-tight connection between the supply pipe and the perforated pipe, a. rotatable shaft, gearing connecting the shaft and perforated pipe whereby the pipe is rotated as the shaft is operated, and means for operating the shaft.
